Nvidia probably has the opposite problem - employee stock has appreciated so much that you have to convince them not to retire.

Maybe but people's spending also dramatically goes up as they start making more money. You buy that $5m vacation home at Tahoe, you buy fully-loaded Rivian SUVs, you send your kids to expensive private schools, you fly only first-class on family vacations, and you are back to needing to work more to sustain this lifestyle.
